How can i send an asset pack that i bought on Fab to my co-worker?

Heads up sorry if thats a very noobish question,but i am kind of confused:
I bought an asset pack on Fab, assuming that i get 3d files that i can send to someone to actually work with it in ue5, but seemingly thats not how it works?

Can someone tell me what i need to do so my friend who wants to do the level design can use the assets i bought?
